SECTION 08 7124 SPECIALTY ACCESSIBLE DOOR HARDWARE‐Product specification in Construction Specifications Institute (CSI) 3-Part, 2004 MasterFormat

NOTES TO SPECIFIER:

Go to HTTP://WWW.KROWNLAB.COM/DOWNLOADS to verify that this is the most current version of the specifications.

This specification is intended to assist architecture and interior design professionals in the specification of specialty hardware for interior sliding doors using the Construction Specification Institute’s 3-part SectionFormat.

This section 08 7124 SPECIALTY ACCESSIBLE DOOR HARDWARE is for the Krownlab product lines which meet the‐ operational and opening-force requirements of various Federal and state agencies, including the DOJ's "2010 ADA Standards for Accessible Design", the DOT's "ADA Standards for Transportation Facilities", the ABA standards of the various Federal agencies having jurisdiction, the International Code Council (ICC) A117.1, and HUD's "Fair Housing Accessibility Guidelines". For applications that do not require universal accessibility, the manufacturer’s section 08 7123 SPECIALTY DOOR HARDWARE may be used to specify additional sliding door hardware product lines from‐ Krownlab. Only this section provides specifications for the Ragnar product line by Krownlab.

Sample language is provided for articles in Part 1 - General, Part 2 - Products, and Part 3 - Execution. The sample language, article/ paragraph numbering and overall section format should be edited to fit the design firm’s specifications and the design intent for the project.

Articles and paragraphs of this product specification assume the Project Manual will contain Division 1 General Requirements documents, including close coordination with the following sections as appropriate:

01 2500 “Substitution Procedures”01 3300 “Submittal Procedures”01 4300 “Quality Assurance”01 6200 “Product Options”

01 6600 “Product Storage and Handling Requirements”01 7400 “Cleaning and Waste Management”01 7700 “Closeout Procedures”01 7800 “Closeout Submittals”

If the project manual does not contain these Division 1 sections, appropriate requirements may be provided by the specifier under the appropriate articles within this section.

INSTRUCTIONS:

At paragraphs in blue text , hidden text may be available for guidance in making selections and edits. The specifier can access the hidden text by selecting on the ¶ symbol within Microsoft Word menus; text will be visible but will remain non-printable unless the font is changed from ‘hidden’ status. Once selections are made and other options deleted, blue font color should be changed to black.

Optional items requiring selection by the specifier are enclosed within brackets, e.g. “Color: [white] [black]”. Once selections are made and other options and brackets deleted, blue font color should be changed to black.

At paragraphs in green text, LEED requirements are indicated and should be confirmed with the project’s design intent. These requirements may be deleted if the project is not intended to attain sustainability certification. Once selections are made and other options deleted, green font color should be changed to black

A. Examine door panels and substrates at the door openings, with the specialty door hardware Installer present, for compliance with requirements for installation tolerances, wall and floor construction, and other conditions affecting installation and performance.

B. Proceed with installation only after unsatisfactory conditions have been corrected.

3.2 PREPARATION

A. Attachment points for specialty door hardware may not align with existing framing or blocking locations. Heights and locations for installation of specialty door hardware components are indicated on Drawings.

B. At wood or light-gauge metal framed partitions, ensure the provision and proper installation of additional framing or blocking within the partition’s framing cavity prior to hardware installation.

1. Coordinate the correct location for additional blocking or framing; height of the attachment point is based on the overall height of the door panel; the location for track mounting points is approximately 2-1/4 inches above the top of door panel.

Retain either or both of the articles below, as required.

2. In new construction, ensure appropriate blocking is added in the correct locations during framing, prior to drywall installation.

3. In renovations, partially remove drywall to expose the framing cavity and install appropriate blocking in the correct locations.

Retain either or both of the articles below, as required.



C. Wood or Other Solid Panel Doors: Provide holes and cutouts in glass to receive hardware, fittings, and accessory fittings. Ensure adequate blocking within the core of the wood or other solid door panel, or comply with DHI WDHS.5 "Recommended Hardware Reinforcement Locations for Mineral Core Wood Flush Doors."

1. Comply with specialty door hardware manufacturer's written recommendations for locations and other dimensions for holes and cutouts in glass panels.

D. Glass Doors: Provide holes and cutouts in glass to receive hardware, fittings, and accessory fittings before tempering glass. Do not cut, drill, or make other alterations to glass after tempering.

1. Comply with specialty door hardware manufacturer's written recommendations for locations and other dimensions for holes and cutouts in glass panels.

2. Ensure that glass has been fully tempered or otherwise meets safety glazing requirements of the building code.

a. Unless otherwise indicated, glass shall be of fully tempered type (FT), using horizontal (roller-hearth) process, and fabricated so that when glass is installed, roll-wave distortion is parallel with bottom edge of glass door panel.

3.3 INSTALLATION

A. Install each specialty door hardware item to comply with manufacturer's written instructions. Where cutting and fitting are required to install specialty door hardware onto or into surfaces that are later to be painted or finished in another way, protect specialty door hardware items until finishes have been completed on substrates involved.

1. Set specialty door hardware items level, plumb, and true to line and location. Adjust and reinforce attachment substrates as necessary for proper installation and operation.

a. Track Adjustability: Utilize manufacturer’s standard toothed washer and grooved inside surface of rail to provide levelness and alignment of the track at each attachment point.

b. Door Adjustability: Utilize manufacturer’s concealed Allen-head screw to provide levelness and alignment of the door height at each trolley.

c. Door Stop Adjustability: Utilize manufacturer’s Allen-head screw to properly locate and secure the door stop along the bottom of the track.

d. Trolley Safety Stop: Utilize manufacturer’s concealed plastic retainer to restrain and secure the trollies on the track once each has been installed.

2. Appropriately prepare substrates that are not as indicated for manufacturer-provided anchorage fasteners. Space fasteners and anchors according to manufacturer's written instructions.

a. At Gypsum Board Drywall Finishes: Utilize the manufacturer’s standard substrate spacer and fastener or anchor to prevent drywall from compressing under concentrated forces at the track attachment to the wall, and help maintain the structural integrity and alignment of the hardware system



3.4 ADJUSTING

A. Adjust and check each operating item of door hardware and each door to ensure proper operation or function of every unit. Replace units that cannot be adjusted to operate as intended.

B. Following installation and adjustment, cycle the door panel open and closed 20 times to redistribute the lubricant within the wheels (bearings).

3.5 CLEANING AND PROTECTION

A. Clean adjacent surfaces soiled by specialty door hardware installation.

B. Clean operating items as necessary to restore proper function and finish.

Retain the article below for finishes indicated for hardware components:

C. For “Black Stainless” (Bs) components: With a clean towel, apply a thin coating of petroleum jelly (e.g. Vaseline by Unilever: www.vaseline.us) and buff clean and dry. Test at an obscure location to confirm acceptability of treatment.

D. Provide final protection and maintain conditions that ensure that specialty door hardware is without damage or deterioration at time of Substantial Completion.

3.6 MAINTENANCE

A. Wheels (bearings) should occasionally be lubricated with bearing oil (e.g. SHC 630 Synthetic Gear and Bearing Oil by Exxon Mobil Corp.: www.mobil.com).
